, This supergroup of supergroups is often Alveolates and nicknamed SAR for its components.
Recent analyses of small subunit ribosomal RNA (16S-like rRNA) and actin coding regions confirm the inclusion of oomycetes in the chromophyte lineage (Gunderson et al., 1987; Bhattacharya and Druehl, 1988; Bhattacharya et al., 1991) which Patterson (1989) collectively describes as stramenopiles.
Diatoms, brown algae, golden-brown algae and nonphotosynthetic aquatic fungi are members of a complex evolutionary assemblage recently described as "stramenopiles" (Patterson, 1989).
One commonly encountered group of microscopic eukaryotes was the stramenopiles. Labyrinthuloides haliotidis and Aplanochytrium sp.
Representatives of the stramenopiles were again encountered, as well as members of Rhizaria and Alveolata.
A review of group fililation of stramenopiles
, additional approaches to the question.
Such systems are only starting to emerge for the stramenopiles
(Massana et al., 2014) and for the ciliates (Dunthorn et al., 2012, 2014).
(2013) from the same lake and depth was different between seasons, mostly due to mixotrophic stramenopiles
such as chrysophytes becoming abundant in autumn.
The kinds of organisms detected from analysis of about 200 clones screened included Stramenopiles
, 28%; Nematoda, 20%; Arthopoda, 20%; Alveolates, 12%; Acantharea, 12%; and Crenarchaeota, 8%.
In our rRNA gene diversity survey of biofllm samples, we obtained sequences representing most of the major eukaryotic lineages, including the fungi, animals, green algae, land plants, stramenopiles
, and alveolates (Amaral Zettler, 2002).
